DELL XPS 890 WNDOWS 10 HOME
I was having a sound problem and I called Dell. The sound would always go off after "sleep" and not come back on unless I rebooted. I said that I would post, if Dell fixed it, so here is what they did:
The chipset needed an update so they did that while taking control of my PC.
The Bios needed an update and that was done.
I had a program called "Clean My PC" installed. They said that it was a bad program and caused several problems. With my permission, they removed it.
My PC is fixed and the sound now works as it should. This may not work for others, but it solved my problem.
I hope this works for you.
